図書館に行って， 『数学ガール/ゲーデルの不完全性定理』(結城 浩. ソフトバンククリエイティブ, 2009) 『数学ガール/乱択アルゴリズム』(結城 浩.ソフトバンククリエイティブ, 2011) 『かけ算には順序があるのか』(高橋 誠. 岩波書店, 2011) 『代替医療のトリック』(Singh, Simon & Ernst, Edzard. 青木 薫[訳]. 新潮社, 2010) を借りてきた…

今年もよろしくお願いします…

今年買ったCDは以下の2枚だけだった… “You Take Me, You Make Me"(鈴木 祥子. Bearforest, 2011) “Syoko Suzuki GOLDEN☆BEST — The Ballad of Syoko Suzuki"(鈴木 祥子. ソニー・ミュージックダイレクト, 2011)

“Most Wi-Fi routers susceptible to hacking through security feature”(Naked Security), Stefan Viehböck, an independent security researcher, published a paper on Boxing Day titled “Brute forcing Wi-Fi Protected Setup” to his WordPress blog disclosing a weakness in the configuration of most consumer/SoHo Wi-Fi routers. (snip) So you have now reduced the difficulty of brute forcing the PIN down to 104 (10,000) plus 103 (1,000) or 11,000 possibilities. Some of the routers Viehböck tested did seem to implement a mechanism to slow down the brute forcing, but the worst case scenario allowed him to acquire the keys within 44 hours. Compared with attempting to attack WPA2-PSK directly, this is a cheap and effective attack. As the sub-title of Viehböck’s paper states “When poor design meets poor implementation” security is the loser.

とりあえず，大掃除は終わった…
